This invention relates to yarn moistening devices useful with textile machinery, particularly with flat full fashioned hosiery machines and the like.

[g To facilitate working of the yarn by the loop forming instrumentalities of hosiery or other knitting machines, it is necessary that they be properly conditioned, i.- e. rendered pliable through application of moisture.

This was ordinarily accomplished heretofore by passing the yarns between opposing felt pads soaked with water or other moisten ing fluid. Under the indicated method, it was difficult to predetermine uniform moistenng of the yarns or to maintain an even tension on them with attendant defects in the knitting from these causes. Moreover, irregularities like small knots or burrs would not readily pass through the pads and would '80 hereby either strain or cause rupture of the yarns with resultant press offs in the machines.

My invention is directed toward overcoming the several drawbacks of previous prac- 5 ice above pointed out, through provision o a simple and inexpensive device whereby, incident to continuous passage of the yarn through it, just the requisite amount of moisture is applied and a predetermined uniform 1S0 "ension induced and maintained regardless,

of irregularities in the yarn. I

In connection with moistening devices of the kind particularly referred to- I moreover aim to facilitate their ready and quick atachment to and detachment from moisture troughs with which they are to be associated, as well as to render disassembling of their component parts very easy for purposes of cleaning and inspection.

"Still other objects and attendant advantages of this invention will be manifest from the following detailed description of the attached drawing, wherein Fig. I is a plan view of my improved moistening device showing the same in association with the trough containing liquid which is to be applied to the yarn.

Fig. II is a sectional view, taken as indicated by the arrows IIII in Fig. I; and, Fig. III is a sectional view, at right angles if that thediskfS is sustainedabove the trough";

to the plane of Fig, II, and takenas' indicated by the-arrows III'III in Fig. I.-= As herein delineated, the yarn moistenin'g device of my invention comprises a bridge piece 5 designed for placementcrosswise of a pan .or trou gh 6containing water or-o-ther moistening liquid L. The bridge piece:5 may be conveniently made of a hollow rectangular configuration from sheet metal with Y spaced notches 7 ,in' the lower edgesof itsopposite sides to engage overtheJlongitudinaL edges of thevtrough 6; The device further comprises a member .'8-.having thexfor'm of a disk with trnn-nionsf 9-.-engagedfor free rotation ein vertical notchesror slotslO at the sides'of the bridge ;piece-5,:"and with'hub extensions 11 to'prev-ent lateral. play within said. bridge piece; As. a consequence of the described arrangement, the disk I '8. can-be lifted upward out of-the slots 10ureadily and thus; removed from the; bridge. piec'e 5 for thepurpose of inspection and cleaning. Res

ferring.- to .-Figs.., II and III,v awm fbeifihserved thatthedepth of'thei slots '10 is-such 6 with ,a limited. extent of ;its lower portion dippinginto the, moistenirrg liquid L, and thatLSaid-disk i'sformed with aacircu'mfeizential groove \l2, in this instance'ofV-shaped cross. sectional;configuration, forxguidance of theyarn Y .which is tobe moistened, and for carrying .up. liquid .L from the trough '6:

to said yarn by.cap'illary action. For

purpose of determining contactof the yarn Y over a predetermined circumferential-extent inover-travelling the disk: 8,5 as shown. in Fig. II, I: provide the bridge piece :5 inits x opposite ends with guide eyes 13 of porcelain or the like in the plane of the groove =12fof.

. said disk.

w i v V I furthermore. equip the device, .witha ten-1 G sioning means. having. the form of a; spring finger 15, the; same being secured; to the bridge piece 5 by a screw-16 and provided at its free end with aneye 17 for passage of u s theyarnY o Incident to. operation eithedevice,- -the, yarn. ,Y in over-travelling the freely revolving disk 8 will propel the same, and absorb moisture carried up to it by the ci'rcumferis absolutely precluded irrespective of knots or burrs so that a uniform tension can be maintained by the spring finger l5 incident to feeding said yarn to the loop forming instrumentalities of the knitting machine.

Having thus described my invention, I claim 1. A yarn moistening device comprising a receptacle for the moistening liquid, a hollow bridge-piece removably supported by opposed notches in its lower edges on the receptacle, a freely rotatable disk detachably iournaled in the bridge-piece with hub extensions to prevent lateral play, said disk 7 being adapted to be propelled by the yarn i11- cident to being overtravelled by the latter and having a circumferential V-groove to carry up moisture from the receptacle by capillary action for absorption by the yarn, and a springy element projecting from the bridge-piece with means for imposing tension upon the yarn.

2. A yarn moistening device comprising a receptacle for the moistening fluid,'ahollow rectangular bridge-piece removably supported against displacement over the receptacle by opposed vertical notches proximate its )wer angular corners, a freely rotatable removable disk journaled in vertical notches extending downward from the top edges of the bridge-piece with hub extensions to prevent lateral propelled by the yarn incident overtravelled by the latter, into the liquid and having V-groove to carry up moisture from the trough by capillary action for absorption by lie yarn guide eyes in the bridge-piece in the plane of the disk V-groove and the axis of rotation to predetermine contact of the yarn over a definite circumferential portion of said disk, and a spring element projecting :om the bridge-piece having an eye for maintaining the yarn under tension.

3. A yarn moistening device comprising a receptacle for the moistening liquid, a 1101- low rectangular bridge-piece removably susained against displacement over the receptacle, a freely rotating removable disk journaled in opposed vertical notches extending downward from the top edges of the bridgepiece and adapted to be propelled by the yarn incident to being overtravelled by the latto being play and adapted to be ter, said disk dipping into the liquid and having a circumferential V-groove to carry up moisture from the trough by capillary action for absorption by the yarn, and a spring finger secured to one side of the bridge-piece with an eye at its free end in the plane of the disk groove for maintaining the yarn under tension during passage through the device.

In testimony whereof, I have hereunto signed my name at Lansdale, Pennsylvania, this 14th day of September, 1929.
